STEAM-VAPOR SPRAY.

Specification of Letters Patent.

Application filed Gctober 30, 1912.

Patented July 28, 1914-. Serial No. 728,602.

To all whom it may concern llc it known that I, WILLIAM H. GO'UGH, acitizen of the United States of America and a resident of Valley Falls,in the State of Rhode Island,havc invented a new and useful Improvementin Steam-Vapor Sprays, of which the following is a specification,

This invention relates to those sprayers or lnimidifiers known as steamvapor sprays which are supplied with steam only. An 0bjecticn to thesedevices as employed in the weaving' rooms of cotton mills is theoccasional discharge of drops of the water of condensation with thevapor spray. Some of them are constructed with special reference toconverting the water of condensation into spray, and I know of none inwhich the Occasional discharge of drops of "ater is ctli'ectivelyprevented.

The leading object of the present invention is to insure the absence ofall water of condensation from the spray,

Another object is to facilitate discharging the spray from each devicethrough a pluralitv of horizontal nozzles with reference especially tothe location of the device in an alley between looms and the dischargeof the spray l'iorizontally on both sides of thc alley above the loomson its respective sides so as to reduce the number of instalmentsrequired for a given area,

Other objects will be set forth in the general description whichfollows.

A sheet of drawings accompanies thls specification as part thereof.

Figure 1 is an elevation partly in section; Fig. 2 represents alongitudinal section through one of the nozzles; Fig. 3 is an end viewof a nozzle.

Like reference characters refer to like carts in all the figures. In theii'nproved apparatus, a steam pipe (1 leads horizontally into avertically elongated hollow member 7), conveniently round incrosssection and of any required length, forming a vertically extendedexpansion chamber, 0, free from partitions, in which the steam isreduced to water vapor of suitable quality. This chamber need not bemore than two inches in diameter. The delivery end a of the steam pipewithin the chamber 0, is extended downward from a point above mid-heightat which the pipe enters, so as to facilitate and insure the escape ofwater of condensation downward. therefrom From a central terminal collarat the domed and otherwise closed upper end of the chamber a connectingpipe (I extends to the required height, and is coupled by a T c, tooppositely projecting horizontal pipes f and g, each terminating in asuitable vapor-spray nozzle 72, one of which is reprcsentcd in detail byFigs. 2 and 3. The aperture 2? in each nozzle is round and axial, andmay be one-sixteenth of an inch in diametcr being in all cases muchsmaller than the inlct chamber of the nozzle. See Fig. 2.

A drip pipe extends downward from the lower end of the chamber 6, withinwhich *atcr of condensation nut accuinulate as represented in Fig. 1,but never so as to be discharged with the vapor-spray. Should thedischarge of this water through the drip pipe j be neglected, itscontact with the steam inlet a will give audible notice of that fact.

Simple globe valves, 1, 2, 3, 4, provide respectively (1) forcontrolling the How of steam through the steam pipe (2, (2 and 3) forregulating the discharge of vapor-Spray -from the several nozzles, and(4;) for regulating the discharge of the water of condensation tl'iroughthe drip pipe j. All the globe valves 1, 2, 3, 4, are readily located soas to be easily accessible; and they are the only parts of the apparatusrequiring repairs; which consist in replacing one or more of the valvedisks, at a cost of a few cents.

The pair of horizontal pipes f and g, each about six inches long, aredesigned to 'etl'ectively locate the vapor-spiny nozzles ii on oppositesides of a weaving-room alley, so as to discharge the spray from one andthe same apparatus over two looms.

One or more additional horizontal pipes may obviously be added; orvapor-spray nozzles of a different pattern, or having apertures of otherforms, may be substituted for those shown; and other like 1nodificationswill suggest themselves to those skilled in the art.

Any apparatus in which water is sprayed however foreign to the presentinvention. It will be seen that in the hereinbefore described apparatusthe only discharge is of steam vapor spray from which water ofcondensation has been separated (1) by the downwardly directed steaminlet a (2) by the top of the expansion chamber 0, (3) by the T e or itsequivalent at the top of the vertical pipe (Z and (4:) by the inletchambers of the vapor nozzles h, these chambers being large comparedwith the axial discharge apertures i as shown in Fig. 2.

Having thus described said improvement, I claim as my invention, anddesire to patent under this specification:

1. A steam-vapor-spray apparatus conr prising a steam-supply pipe havinga clownwardly extended delivery end, a vertically elongated hollowmember forming a vertically extended expansion chamber into which saidpipe extends horizontally, said chamber member having a central terminalcollar at its domed and otherwise closed upper end, a pipe extendingvertically upward from said collar, a coupling at the upper end of thispipe, a plurality of horizontal pipes in communication with said chamberthrough said coupling and said vertically extending pipe, vapor-spraynoz zles having drip-preventing chambers at the extremities of saidhorizontal pipes, and

a means for draining said expansion chamber.

2. In a vapor-spray apparatus supplied with steam only, the combinationwith a horizontal steam pipe, of a vertically elongated hollow memberforming a vertically extended expansion chamber into which said steampipe extends above mid-height of the chamber, and within which said pipeis eX- tended downward, said chamber member having a central terminalcollar at its domed and otherwise closed upper end, a pipe extendingvertically upward from said collar,

and means for regulating the flow through each of said horizontal pipesand through said drip pipe, substantially as hereinbefore specified,
